Typically will be the same for all toyotas 86-95ish
Some MK2's apparently have some sort of diagnosis system but I'm not sure which ones exactly, it's apparently a 2pin plug with a cap on it that you short.

MKIII trouble code 26
This is a great forum/thread! I read through the previous 4 pages and didnt see anything on code 26 on 1990 turbo supra, and this code is not in the manual. Just bought the car a month ago and have been restoring it to stock. Everything has been going well until it started intermittently started cutting of all power under heavy acceleration. It always havens from about 3000you rpm and up. Anyone ever had a problem with this code?
